➀ Amp draw data shown is operating amp draw at incoming power. For units that use a field installed accessory step-down transformer
as noted, the amp draw shown is the primary side operating amp draw. For sizing of circuit protection for equipment with National
Electric Code.transformers, please refer to the Amp draw data shown is operating amp draw at incoming power. For units that use a
field installed accessory step-down transformer as noted, the amp draw shown is the primary side operating amp draw. For sizing of
circuit protection for equipment with transformers, please refer to the National Electric Code.
➁ For PTP units that are used on 230V/1ph, all models are equipped with 115V motors except the PTP400 which is equipped with
motors that can operate on 230V. Since the transformer does not need to be sized to include the propeller motor, the rating of the
Step Down Transformer Accessory is sized smaller for the power exhauster and gas control circuit only.
